Rectal cancer is one of the most common malignant tumors in the world. However, there's also no reliable and sensitive method to monitor diseases and evaluate therapy responses till now. Circulating tumor cells, which could reflect tumor's status correctly and reliably, may be a promising method in this field. This study is to investigate the role of circulating tumor cells in evaluating and predicting the responses of chemoradiotherapy in rectal cancer.

Primary Outcome Measures:
  • circulating tumor cells level changes after radiotherapy [ Time Frame: 3 years ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • overall survival [ Time Frame: 3 years ] [ Designated as safety issue: Yes ]
  • disease-free survival [ Time Frame: 3 years ] [ Designated as safety issue: Yes ]
  • serum carcinoembryonic antigen (CEA) level [ Time Frame: 3 years ] [ Designated as safety issue: Yes ]
  • pathological response (tumor regression grade)if surgery [ Time Frame: 3 years ] [ Designated as safety issue: Yes ]
  • RECIST-based tumor response at 10 week after radiotherapy [ Time Frame: 3 years ] [ Designated as safety issue: Yes ]
